Description

Technical Field

[0001] The present application relates to the field of communications, and more specifically, to a communication method and a communication device. Background Art

[0002] As a new type of aircraft, uncrewed aerial vehicle (UAV) has become increasingly popular due to its flexibility and convenience. Cellular networks can provide UAVs with important features such as wide coverage, high reliability, high security, and continuous mobility, as well as supervision by regulators. The communication environment of UAVs is quite different from that of ordinary user equipment (UE). UAVs mainly fly above base stations and connect to base stations through Uu ports, mainly communicating in line of sight (LOS). Therefore, UAVs can receive signals from more base stations.

[0003] There may be a risk of collision when drones are flying in the air. In order to avoid collisions between drones, the current 3rd generation partnership project (3GPP) system supports a detect and avoid mechanism (DAA); on the other hand, regulators require drones to broadcast their identifiers (ID) during flight to facilitate continuous management of drones. The 3GPP system supports broadcast UAV IDs (BRID). It can also be understood that the services currently supported by drones include BRID services, DAA, and command and control (C2) services (where C2 is the communication between the drone and the controller). At present, 3GPP has defined the standard PC5 interface 5G QoS identification (PC5 PQI) (hereinafter referred to as "PQI") to indicate the different services supported by drones.

[0004] The current standard has stipulated that the base station can configure a dedicated resource pool for the drone, which can support the drone to transmit data for DAA services and / or BRID services. However, for the drone, when data arrives, if a non-standard PQI is used or no PQI is used, the drone cannot distinguish which service the arriving data is used for based on the standard protocol. Therefore, the drone may not transmit data of the corresponding service type on the resource pool configured by the base station, which may cause transmission errors and affect the user's service experience. Summary of the invention

[0005] The present application provides a communication method, in which a terminal device can distinguish data of different service types based on indication information, and instruct a network device to allocate resources of the service type through the indication information. Therefore, the terminal device can subsequently send data of the corresponding service type on the corresponding resources configured by the network device, which can avoid transmission errors caused by the terminal device and ensure the user's service experience.

[0006] In a first aspect, a communication method is provided, which is applied to sidelink communication, and the method can be executed by a terminal device, or can also be executed by a component (such as a chip or circuit) of the terminal device, without limitation. For example, the terminal device can be a drone, an aerial vehicle, and the like.

[0007] The method includes: the terminal device obtains a first quality of service QoS parameter and indication information, the indication information is used to indicate the service type corresponding to the first data, the first QoS parameter is the QoS requirement parameter of the first data of the terminal device, the terminal device sends first information to the network device, and the first information includes the indication information.

[0008] In a possible implementation manner, the first QoS parameter is a QoS parameter not defined by the Third Generation Partnership Project 3GPP.

[0009] In the present application, "the first QoS parameter is a QoS parameter not defined by 3GPP" can also be understood as "the first QoS parameter is a QoS parameter corresponding to a service type not specified by the 3GPP standard".

[0010] In a possible implementation scenario, "parameters not defined by 3GPP" can be understood as a private parameter, not a parameter specified in the protocol. For example, assuming that the QoS parameter is PQI, the protocol defines that when the PQI value is 40 to 44 and 62 to 65, each has a corresponding service type. The "first QoS parameter" in this application can be understood as a PQI value of 10 or a PQI value of 100. At this time, the protocol does not specify the corresponding service type when the PQI value is 10, nor does it specify the corresponding service type when the PQI value is 100.

[0011] In another possible implementation scenario, "parameters not defined by 3GPP" can be understood as, although the parameters defined in 3GPP are used, the corresponding service type is not defined in the protocol. For example, assuming that the QoS parameter is PQI, and the protocol defines that when the PQI value is 42, the corresponding service type is C2 service; when the PQI value is 62, the corresponding service type is BRID service; when the PQI value is 64, the corresponding service type is DAA service. The "first QoS parameter" in this application can be understood as, when the PQI value is 42, the corresponding service type defined in the terminal device is DAA service; when the PQI value is 62, the corresponding service type defined in the terminal device is C2 service; when the PQI value is 64, the corresponding service type defined in the terminal device is BRID service.

[0012] Optionally, the terminal device may determine whether the QoS parameter is the first QoS parameter or the second QoS parameter, wherein the second QoS parameter may be understood as "the QoS parameter defined by 3GPP" or "the QoS parameter corresponding to the service type specified by the 3GPP standard". Specifically, how the terminal device determines whether the QoS parameter is a parameter specified in the protocol or not a parameter specified in the protocol may be implemented by the terminal device itself and is not limited.

[0013] It should be noted that, in this application, the specific name of the QoS parameter is not limited. For example, the QoS parameter can be PQI or other parameters. As long as the parameter is used to characterize the QoS requirements, it falls within the scope of protection required by this application.

[0014] In the present application, for example, "service type" includes at least one of the following: detection and avoidance of collision DAA service, drone ID broadcast BRID service, command and control C2 service. Exemplarily, the service type corresponding to the first data may include: DAA service type and BRID service type.

[0015] Exemplarily, the first QoS parameter may be obtained by the terminal device from the core network via a non-access stratum (NAS) message.

[0016] Optionally, in the present application, since the terminal device can distinguish the service type corresponding to the data through the obtained indication information, if the network device has pre-configured resources of different service types for the terminal device, the terminal device can directly transmit data of the corresponding service type on the corresponding resources, thereby avoiding transmission errors.

[0017] Based on the above technical solution, in this application, considering that when the QoS parameters are not parameters defined by the standard, the terminal device cannot distinguish the service type of the data through the standard protocol, at this time, this application proposes that the terminal device can determine the first indication information inside, and the indication information is used to indicate the service type corresponding to the data. The terminal device can also send the first indication information to the network device to indicate the allocation of resources of this service type to the network device, so that the terminal device can send service data of the corresponding service type on the resources configured by the network device. The resources configured by the network device can be used correctly to avoid transmission errors. For example, the terminal device can transmit DAA service data on the DAA dedicated resources configured by the network device, the terminal device can transmit BRID service data on the BRID dedicated resources configured by the network device, and the terminal device can transmit ordinary service data on ordinary resources configured by the network device.

[0018] In a possible implementation, the indication information is used by the network device to allocate resources corresponding to the service type to the terminal device.

[0019] Based on the above technical solution, in this application, the network device can configure resources of the corresponding service type for the terminal device based on the indication information, and the terminal device can transmit data of the corresponding service type on the resources configured by the network device to avoid transmission errors and ensure the user's service experience.

[0020] In a possible implementation, the indication information is obtained from an upper layer of the terminal device, and the upper layer of the terminal device sends it to a lower layer; or, the indication information is obtained by the terminal device according to the first data. For example, the upper layer of the terminal device determines the indication information according to the first QoS parameter. For another example, the upper layer of the terminal device determines the indication information according to the first data.

[0021] In the present application, the “upper layer of the terminal device” may be understood as, for example, an A2X layer or an application layer; the “lower layer of the terminal device” may be understood as, for example, a physical layer or an access layer.

[0022] In a possible implementation manner, the indication information is used to indicate a service type corresponding to a quality of service QoS flow.

[0023] In a possible implementation manner, the first information further includes a layer 2 identifier L2 ID, and the indication information is used to indicate a service type of data of a terminal device corresponding to the L2 ID.

[0024] In the present application, L2 ID is an L2 identifier of a destination, and L2 ID can be used to indicate a terminal device.

[0025] In a possible implementation manner, the indication information is used to indicate the service type corresponding to the QoS flow associated with the L2 ID.

[0026] In a possible implementation manner, the service types corresponding to the QoS flows are the same.

[0027] In one possible implementation, the method also includes: determining a first resource allocated by the network device, the first resource being used to transmit data of a first service type; sending a first transmission block to the network device on the first resource, wherein the service types corresponding to the data in the first transmission block are the same, the service type corresponding to the data in the first transmission block is the first service type, and the data in the first transmission block is part or all of the first data.

[0028] Based on the above technical solution, in this application, by limiting the data of the same service type to be grouped into the same transmission block, it is ensured that data of other service types will not be transmitted on the dedicated resources allocated by the network device to the terminal device, thereby avoiding transmission errors.

[0029] In a second aspect, a communication method is provided, which is applied to sidelink communication. The method can be executed by a network device, or can also be executed by a component of the network device (such as a chip or circuit), without limitation. For example, the network device can be a base station,

[0043] Exemplarily, the second QoS parameter may be obtained by the terminal device from the core network via a non-access stratum (NAS) message.

[0044] Exemplarily, the “service type” in the present application may include at least one of the following: detection and avoidance of collision DAA service, drone ID broadcast BRID service, command and control C2 service.

[0045] Based on the above technical solution, in this application, when the QoS parameter is a parameter defined by the standard, the terminal device can distinguish the service type of the data through the standard QoS parameter, and the terminal device can also send the QoS parameter to the network device. The terminal device can send data of the corresponding service type on the resources configured by the network device, so that the resources configured by the network device can be properly utilized to avoid transmission errors. For example, the terminal device can transmit DAA service data on the DAA dedicated resources configured by the network device, the terminal device can transmit BRID service data on the BRID dedicated resources configured by the network device, and the terminal device can transmit ordinary service data on ordinary resources configured by the network device.

[0046] In a possible implementation, the second QoS parameter is used by the network device to allocate resources corresponding to the service type to the terminal device.

[0052] Based on the above technical solution, in this application, by limiting the data of the same service type to be grouped into the same transmission block, it is ensured that data of other service types will not be transmitted on the dedicated resources allocated by the network device to the terminal device, thereby avoiding transmission errors.

Satellite communication system, future communication system, such as a sixth generation (6G) mobile communication system, or a fusion system of multiple systems.

[0097] The network device may be an entity on the network side for transmitting or receiving signals. The network device may be an access device for a communication device to access the wireless communication system in a wireless manner, for example, the network device may be a base station. The base station can broadly cover the following various names, or be replaced with the following names, such as: NodeB, evolved NodeB (eNB), next generation NodeB (gNB), access network equipment in open radio access network (O-RAN), relay station, access point, transmission point (transmitting and receiving point, TRP), transmission point (transmitting point, TP), master station MeNB, secondary station SeNB, multi-standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), radio head (RRH), central unit (CU), distributed unit (DU), radio unit (radio unit, RU), centralized unit control plane (CUcontrol plane, CU-CP) node, centralized unit user plane (CU user plane, CU-UP) node, positioning node, etc. The base station can be a macro base station, a micro base station, a relay node, a donor node or the like, or a combination thereof. The network device may also refer to a communication module, a modem or a chip used to be arranged in the aforementioned device or apparatus. The network device may also be a mobile switching center and a device to device (Device-to-Device, D2D), vehicle external connection (vehicle-to-everything, V2X), a device that performs the base station function in machine-to-machine (machine-to-machine, M2M) communication, a network side device in a 6G network, and a device that performs the base station function in a future communication system.

The present application does not completely limit the above-mentioned protocol stack segmentation method, and there may be other segmentation methods. For details, please refer to the technical research report (technical report, TR) 38.801v14.0.0.

[0099] The terminal device in this application may include a drone, an aerial vehicle, for example, an airship, a glider, a hot air balloon, a jet backpack, and the like.

[0100] As a new type of aircraft, uncrewed aerial vehicle (UAV) has become increasingly popular due to its flexibility and convenience. Cellular networks can provide drones with important features such as wide coverage, high reliability, high security, and continuous mobility, as well as supervision by regulators. The communication environment of drones is quite different from that of ordinary user equipment (UE). They mainly fly above base stations and are connected to the base stations through the Uu port. They mainly communicate in the line of sight (LOS) path. Therefore, drones can receive signals from more base stations. Figure 1 As shown, the drone can communicate with base station #1, base station #2, and base station #3 at the same time.

[0101] There may be a risk of collision when drones are flying in the air. In order to avoid collisions between drones, the current 3rd generation partnership project (3GPP) system supports a detect and avoid mechanism (DAA). Among them, network-assisted DAA and PC5-based DAA are included. Specifically, for network-assisted DAA, the unmanned aircraft system traffic management (UTM) obtains the flight path of each drone during the drone flight authorization process or application layer reporting. In some cases, the flight paths of different drones overlap or are in the same area. UTM can request the 5G system (5GS) to perform DAA between any two drones whose flight paths may overlap or are in the same area. The network determines the collision risk of the drone based on the flight path reported by the drone. If there is a collision risk, the network sends instructions to the UE to avoid collision. Network-assisted DAA is very useful for scenarios where regulations may consider sidelink transmission to be unresolvable or the PC5 connection of the drone is unavailable. For DAA based on PC5 port, the UAV directly broadcasts DAA messages (for example, location information, etc.) through PC5 port. After receiving the DAA message, the peer UAV determines the collision risk. If there is a collision risk, it sends a collision resolution message to the peer UE, and the peer UE replies with a collision resolution response message. On the other hand, regulators require UAVs to broadcast the UAV ID during flight to facilitate continuous management of the UAV. The 3GPP system supports UAV ID broadcast (Broadcast UAV ID, BRID), including BRID based on multicast broadcast service (MBS) and BRID based on PC5 port. BRID based on MBS uses the existing MBS to broadcast the UAV ID. BRID based on PC5 port is similar to DAA. The UAV broadcasts through PC5 port. Figure 2 The DAA scenario and BRID scenario introduced above are shown. For example, DAA services can be conducted between drone #1 and drone #2, and BRID services can be conducted between drone #1 and the regulatory agency.

[0102] The Uu interface allocates resources based on resource blocks (RBs), while the sidelink allocates channel resources based on "resource pools". The existing new radio (NR) sidelink system already supports the configuration of up to 8 resource pools for ordinary sidelink communications. Here, "ordinary sidelink communications" refer to other sidelink communications except sidelink relay discovery. For sidelink relay discovery, a dedicated resource pool is defined in the protocol, that is, the resource pool can only be used to send sidelink relay discovery messages.

[0103] There are two ways to obtain resources for Sidelink, namely base station scheduling mode (mode1) and user equipment (UE) selection mode (mode2). In base station scheduling mode (mode1), the base station can indicate which resource pool the currently scheduled resources belong to by carrying the resource pool (RP) index in the downlink control information (DCI). After receiving the scheduled sidelink resources, the UE will first determine which destination data to send, and then determine which logical channel data of the destination to send. Among them, "destination" can be a unicast, multicast or broadcast. Simply put, it is to see which destination has the highest priority for the data to be transmitted among all destinations, and then select the destination, and then sort the cached data and media access control element (MAC CE) in each logical channel in the destination, and give priority to sending high-priority data or MAC CE.

[0104] 3GPP defines the aerial to everything (A2X) layer for drone services. A2X communicates based on the PC5 port and transmits based on the sidelink. A2X includes BRID, DAA and command and control (C2) communications (C2 is the communication between the drone and the controller). The existing standard introduces an additional resource pool for drones, the A2X resource pool, for example, DAA dedicated resources transmit DAA service data, and BRID dedicated resource pools transmit BRID services. Specifically, when the base station broadcasts the SIB message, additional indication information can be added to the A2X resource pool to indicate that the resource is used for DAA services and / or BRID services. At present, 3GPP defines the standard PC5 interface 5G service quality indication information (PC5 5G QoS identification, PC5 PQI) (hereinafter referred to as "PQI") to indicate the different services supported by drones, see technical specification (TS) 23.256, which defines the specific PQI values ​​and their corresponding specific A2X service types.

[0105] The current standard has stipulated that the base station can configure a dedicated resource pool for the drone, which can support the drone to transmit data for DAA services and / or BRID services. However, for the drone, when data arrives, if a non-standard PQI is used or no PQI is used, the drone cannot distinguish the specific service the arriving data is used for based on the standard protocol. Or, when service data arrives at the upper layer, if the upper layer uses a non-standard PQI or no PQI is used, the drone lower layer cannot distinguish the specific service the arriving service data is used for based on the standard PQI protocol. Therefore, the drone may not transmit data of the corresponding service type on the resource pool configured by the base station, resulting in transmission errors.

[0106] In view of this, the present application provides a communication method, when the terminal device determines that the PQI is not a standard PQI (or, when the upper layer of the terminal device determines that the PQI is not a standard PQI), the terminal device can obtain indication information, and the indication information is used to indicate the service type corresponding to the data. The terminal device can also send a first indication information to the network device to instruct the network device to allocate resources of this service type. Subsequently, the terminal device can send service data of the corresponding service type on the resources configured by the network device, so that the resources configured by the network device can be correctly utilized to avoid transmission errors. For example, the terminal device can transmit DAA service data on the DAA dedicated resources configured by the network device, the terminal device can transmit BRID service data on the BRID dedicated resources configured by the network device, and the terminal device can transmit ordinary service data on ordinary resources configured by the network device.

[0107] Figure 3 This is a schematic diagram of a scenario applicable to this application, such as Figure 3 As shown, the application scenario is that the drone determines the service type corresponding to the service data during flight and reports the service type to the network device.

[0108] Figure 4 is a schematic flow chart of a communication method 400 provided in the present application, such as Figure 4 As shown, the method includes:

[0109] 410. The terminal device obtains a first QoS parameter and / or indication information, where the indication information is used to indicate a service type corresponding to the first data, and the first QoS parameter is a QoS requirement parameter of the first data of the terminal device.

[0110] Exemplarily, the first QoS parameter is a QoS parameter not defined by 3GPP.

[0111] The "first data" in this application can be understood as data from an upper layer. The "data" in this application can also be replaced by "business data".

[0112] In the present application, "the first QoS parameter is a QoS parameter not defined by 3GPP" can also be understood as "the first QoS parameter is a QoS parameter corresponding to a service type not specified by the 3GPP standard".

[0113] In a possible implementation scenario, "parameters not defined by 3GPP" can be understood as a private parameter, not a parameter specified in the protocol. For example, assuming that the QoS parameter is PQI, the protocol defines that when the PQI value is 40 to 44 and 62 to 65, each has a corresponding service type. The "first QoS parameter" in this application can be understood as a PQI value of 10 or a PQI value of 100. At this time, the protocol does not specify the corresponding service type when the PQI value is 10, nor does it specify the corresponding service type when the PQI value is 100.

[0114] In another possible implementation scenario, "parameters not defined by 3GPP" can be understood as, although the parameters defined in 3GPP are used, the corresponding service type is not defined in the protocol. For example, assuming that the QoS parameter is PQI, and the protocol defines that when the PQI value is 42, the corresponding service type is C2 service; when the PQI value is 62, the corresponding service type is BRID service; when the PQI value is 64, the corresponding service type is DAA service. The "first QoS parameter" in this application can be understood as, when the PQI value is 42, the corresponding service type defined in the terminal device is DAA service; when the PQI value is 62, the corresponding service type defined in the terminal device is C2 service; when the PQI value is 64, the corresponding service type defined in the terminal device is BRID service.

[0115] Optionally, the terminal device may determine whether the QoS parameter is the first QoS parameter or the second QoS parameter, wherein the second QoS parameter may be understood as "the QoS parameter defined by 3GPP" or "the QoS parameter corresponding to the service type specified by the 3GPP standard". Specifically, how the terminal device determines whether the QoS parameter is a parameter specified in the protocol or not a parameter specified in the protocol may be implemented by the terminal device itself and is not limited.

[0116] It should be noted that, in this application, the specific name of the QoS parameter is not limited. For example, the QoS parameter can be PQI or other parameters. As long as the parameter is used to characterize the QoS requirements, it falls within the scope of protection required by this application.

[0117] In the present application, for example, "service type" includes at least one of the following: detection and avoidance of collision DAA service, drone ID broadcast BRID service, command and control C2 service. Exemplarily, the service type corresponding to the first data may include: DAA service type and BRID service type.

[0118] Exemplarily, when the bit value in the indication information is "01", it is used to indicate the DAA service, and when the bit value in the indication information is "10", it is used to indicate the BRID service. Exemplarily, the indication information can indicate different service types by multiplexing the name of a QoS field in the PQI, for example, the name of a QoS field in the PQI is DAA-QoS, or the name of a QoS field in the PQI is DAA-QoS.

[0119] In the present application, “the terminal device obtains the first QoS parameter and / or indication information” may be implemented in the following manners, for example:

[0120] Method 1

[0121] In another possible implementation, the terminal device obtains a first QoS parameter, the upper layer of the terminal device sends the first QoS parameter to the lower layer, and the lower layer of the terminal device determines that the first QoS parameter is not a QoS parameter defined by the standard. Therefore, the lower layer of the terminal device can determine the indication information based on the first QoS parameter and / or based on the first data.

[0122] Method 2

[0123] In one possible implementation, the terminal device obtains a first QoS parameter, and the terminal device determines the first QoS parameter, which is not a QoS parameter defined by the standard. Therefore, the upper layer of the terminal device can determine the indication information based on the first QoS parameter and / or based on the first data, and send the indication information to the lower layer.

[0124] Method 3

[0125] In another possible implementation, the terminal device obtains a first QoS parameter, and the upper layer of the terminal device determines the first QoS parameter, which is not a QoS parameter defined by the standard. Therefore, the upper layer of the terminal device can determine the indication information based on the first QoS parameter and / or based on the first data, and send the first QoS parameter and the indication information together to the lower layer.

[0126] Method 4

[0127] In a possible implementation, the upper layer of the terminal device may determine the indication information according to the data, and send the indication information to the lower layer. Alternatively, the lower layer of the terminal device may determine the indication information according to the data.

[0128] It should be noted that in mode 4, the terminal device only obtains the indication information at the beginning, but does not obtain the first QoS parameter. Subsequently, the terminal device may receive the first QoS parameter from the core network through a NAS message.

[0129] In the present application, the “upper layer of the terminal device” may be understood as, for example, an A2X layer or an application layer; the “lower layer of the terminal device” may be understood as, for example, a physical layer or an access layer.

[0130] Optionally, in the present application, since the terminal device can distinguish the service type corresponding to the data through the obtained indication information, if the network device has pre-configured resources of different service types for the terminal device, the terminal device can directly transmit data of the corresponding service type on the corresponding resources, thereby avoiding transmission errors.

[0131] 420. The terminal device sends the first information to the network device, where the first information includes the indication information.

[0132] Correspondingly, the network device receives the first information.

[0133] In the present application, the indication information can be used by the network device to allocate resources corresponding to the service type to the terminal device.

[0134] Exemplarily, the first information may be sidelink UE information (SUI).

[0135] In a possible implementation, the indication information may directly indicate the service type at the QoS flow granularity. It can also be understood that the indication information is used to indicate the service type corresponding to each QoS flow. Exemplarily, the indication information may uniformly indicate the service type corresponding to all QoS flows; Exemplarily, the indication information may also separately indicate the service type corresponding to each QoS flow. The specific implementation is not limited in this application.

[0136] In another possible implementation, the first information may further include a layer 2 identifier L2 ID, wherein the L2 ID is used to indicate a terminal device. In this case, the indication information may be used to indicate the service type of the data of the terminal device corresponding to the L2 ID. Exemplarily, the destination terminal may be determined by the L2 ID, and in this case, the indication information may specifically indicate the service type corresponding to the terminal device. Assuming that the first information includes L2 ID#1, in a possible implementation, the indication information may indicate that the service type corresponding to the L2 ID#1 is a DAA service.

[0137] In another possible implementation, if multiple QoS flows are associated with the L2 ID, the indication information can be used to indicate the service type corresponding to each of the multiple QoS flows. Exemplarily, assuming that there are two QoS flows under L2 ID#1, namely QoS flow #1 and QoS flow #1#, the indication information includes field #1 and field #2, wherein field #1 is used to indicate that the service type is a DAA service, and field #2 is used to indicate a BRID service. The indication information can indicate that the service type corresponding to QoS flow #1 is a DAA service, and the service type corresponding to QoS flow #2 is a BRID service. Exemplarily, assuming that there are 5 QoS flows under L2 ID#2, and the indication information only includes field #1, then field #1 can indicate that the service types corresponding to the 5 QoS flows under L2 ID#2 are all BRID service types. At this point, it can also be understood that the service types corresponding to multiple QoS flows associated with the same L2 ID are the same.

[0138] In the present application, in a possible implementation, in the above-mentioned methods 1 to 1, the first information may also include a first QoS parameter. In another possible implementation, the first QoS parameter may not be sent in the same message as the indication information. For example, the first QoS parameter may be sent to the network device through other signaling after the indication information is sent.

[0139] The above implementation can be understood as being mainly for unicast services. If it is a broadcast service, the service type can be distinguished by directly including the L2 ID in the first information.

[0140] Optionally, the method further includes step 430, in which the network device allocates resources corresponding to the service type to the terminal device according to the indication information.

[0141] In the present application, in a possible implementation, the network device allocates corresponding resources to the terminal device based on the indication information reported by the terminal device. For example, the indication information is used to indicate that the service types include DAA service and C2 service, then the network device can allocate a DAA dedicated resource pool for the DAA service and a common resource pool for the C2 service.

[0142] In another possible implementation, the network device may pre-allocate resources corresponding to each service type for the terminal device. For example, the network device allocates a DAA dedicated resource pool for the DAA service, or allocates a BRID dedicated resource pool for the BRID service and a common resource pool for the C2 service.

[0143] Exemplarily, the network device may indicate the resources allocated to the terminal device by sending configuration information.

[0144] In the present application, “resources” may be frequency domain resources, time domain resources, resource pools, resource blocks (RBs), physical resource blocks (PRBs), etc., and are not limited in the present application.

[0145] Optionally, the method further includes step 440, in which the terminal device determines a first resource allocated by the network device, where the first resource is used to transmit data of a first service type.

[0146] Assuming that the service type corresponding to the first data of the terminal device is the DAA service, and the resource allocated by the network device to the terminal device for transmitting the data of the DAA service is the first resource, the terminal device can determine the location of the first resource.

[0147] Optionally, the method further includes step 450, in which the terminal device sends a first transmission block to the network device on the first resource.

[0148] Correspondingly, the network device receives the first transmission block from the terminal device.

[0149] In the present application, after receiving the sidelink resources scheduled by the network device, the terminal device will first determine which destination data to send, and then determine which logical channel data of the destination to send, and determine that the data to be transmitted has the highest priority among all destinations, then select the destination, and then sort the cached data and media access layer control elements (media access control element, MAC CE) in each logical channel in the destination, and give priority to sending high-priority data or MAC CE. This process can also be understood as the process of the terminal device group transport block (transport block, TB).

[0150] Furthermore, the present application also proposes that the service type corresponding to the data in the transmission block (i.e., the first transmission block) of the terminal device group is the same, that is, the service type corresponding to the data in the first transmission block is the first service type, and the data in the first transmission block is part or all of the first data. For example, if the first service type is a DAA service, the data in the first transmission block is the data of the DAA service type in the first data.

[0151] Based on the above technical solution, considering that when the QoS parameters are not parameters defined by the standard, the terminal device cannot distinguish the service type of the data through the standard protocol. At this time, the present application proposes that the first indication information can be determined inside the terminal device, and the indication information is used to indicate the service type corresponding to the data. The terminal device can also send the first indication information to the network device. Thus, the terminal device can send service data of the corresponding service type on the resources configured by the network device, so that the resources configured by the network device can be correctly utilized to avoid transmission errors. For example, the terminal device can transmit DAA service data on the DAA dedicated resources configured by the network device, the terminal device can transmit BRID service data on the BRID dedicated resources configured by the network device, and the terminal device can transmit ordinary service data on ordinary resources configured by the network device.

[0152] In addition, in the present application, by limiting the data of the same service type to be grouped into the same transmission block, it is ensured that data of other service types will not be transmitted on the dedicated resources allocated by the network device to the terminal device, thereby avoiding transmission errors.

[0153] Figure 5 is a schematic flow chart of a communication method 500 provided by the present application. The same implementation methods in method 500 as those in method 400 are not described again. Method 500 mainly describes the differences from method 400, such as Figure 5 As shown, the method includes:

[0154] 510. The terminal device obtains a second QoS parameter, where the second QoS parameter is used to indicate a service type corresponding to the second data, wherein the second QoS parameter is a QoS requirement parameter of the second data of the terminal device, and the second QoS parameter is a QoS parameter defined by 3GPP.

[0155] In the present application, "the second QoS parameter is a QoS parameter defined by 3GPP" can also be understood as the second QoS parameter is a QoS parameter corresponding to the service type specified by the 3GPP standard. For example, the QoS parameters defined by 3GPP can refer to the parameters defined in TS38.331, and of course also include the QoS parameters newly defined in 3GPP in the future. For example, different PQI values ​​defined in TS23.256 can indicate different service types.

[0156] Exemplarily, the second QoS parameter may be obtained by the terminal device from the core network via a NAS message.

[0157] Exemplarily, the “service type” in the present application may include at least one of the following: detection and avoidance of collision DAA service, drone ID broadcast BRID service, command and control C2 service.

[0158] In a possible implementation, after the terminal device obtains the second QoS parameter, it may also generate second indication information based on the second QoS parameter and / or the second data, where the second indication information is used to indicate the service type corresponding to the second data.

[0159] 520. The terminal device sends second information to the network device, where the second information includes a second QoS parameter.

[0160] Correspondingly, the network device receives the second information from the terminal device.

[0161] Exemplarily, the second information may be sidelink UE information (SUI).

[0162] In the present application, the second QoS parameter is used by the network device to allocate resources corresponding to the service type to the terminal device.

[0163] In a possible implementation, the second QoS parameter can directly indicate the service type at the QoS flow granularity. It can also be understood that the second QoS parameter is used to indicate the service type corresponding to each QoS flow. Exemplarily, the second QoS parameter can uniformly indicate the service type corresponding to all QoS flows; Exemplarily, the second QoS parameter can also separately indicate the service type corresponding to each QoS flow. The specific implementation is not limited in this application.

[0164] In another possible implementation, the second information may further include a layer 2 identifier L2 ID, wherein the L2 ID is used to indicate the type of the terminal device. In this case, the second QoS parameter may be used to indicate the service type of the data of the terminal device corresponding to the L2 ID.

[0165] In yet another possible implementation, if multiple QoS flows are associated with the L2 ID, the second QoS parameter may be used to indicate service types corresponding to the multiple QoS flows.

[0166] In another possible implementation manner, the service types corresponding to the multiple QoS flows are the same.

[0167] The specific implementation method can be understood by referring to the description and examples related to step 420 in method 400, which will not be repeated here.

[0168] In some implementations, if the second indication information is generated in step 510 , then in step 520 , the second information may also include the second indication information.

[0169] Optionally, the method further includes step 530, in which the network device allocates resources corresponding to the service type to the terminal device according to the second QoS parameter.

[0170] In the present application, in a possible implementation, the network device allocates corresponding resources to the terminal device based on the second QoS parameter reported by the terminal device. For example, the second QoS parameter is used to indicate that the service type includes DAA service and C2 service, then the network device can allocate a DAA dedicated resource pool for the DAA service, and allocate a common resource pool for the C2 service.

[0171] In another possible implementation, the network device may pre-allocate resources corresponding to each service type for the terminal device. For example, the network device allocates DAA-specific resources for DAA services, or allocates BRID-specific resources for BRID services, or allocates common resources for C2 services.

[0172] Optionally, the method further includes step 540, in which the terminal device determines a second resource allocated by the network device, and the second resource is used to transmit data of a second service type.

[0173] Assuming that the service type corresponding to the second data of the terminal device is the DAA service, and the resources allocated by the network device to the terminal device for transmitting the data of the DAA service are second resources, the terminal device can determine the location of the second resources.

[0174] Optionally, the method further includes step 550, in which the terminal device sends a second transmission block to the network device on a second resource.

[0175] Correspondingly, the network device receives a second transmission block from the terminal device.

[0176] In the present application, after receiving the sidelink resources scheduled by the network device, the terminal device will first determine which destination data to send, and then determine which logical channel data of the destination to send, and determine that the data to be transmitted has the highest priority among all destinations, then select the destination, and then sort the cached data and media access layer control elements (media access control control element, MAC CE) in each logical channel in the destination, and give priority to sending high-priority data or MAC CE. This process can also be understood as the process of terminal device group transmission blocks.

[0177] Furthermore, the present application also proposes that the service type corresponding to the data in the transport block (TB) (i.e., the second transport block) of the terminal device group is the same, that is, the service type corresponding to the data in the second transport block is the second service type, and the data in the second transport block is part or all of the second data. For example, if the second service type is a DAA service, the data in the second transport block is the data of the DAA service type in the second data.

[0178] Based on the above technical solution, in this application, when the QoS parameter is a parameter defined by the standard, the terminal device can distinguish the service type of the data through the standard QoS parameter. The terminal device can also send the QoS parameter to the network device. Thus, the terminal device can send the service data of the corresponding service type on the resources configured by the network device, so that the resources configured by the network device can be properly utilized to avoid transmission errors. For example, the terminal device can transmit the data of the DAA service on the DAA dedicated resources configured by the network device, the terminal device can transmit the data of the BRID service on the BRID dedicated resources configured by the network device, and the terminal device can transmit the data of the ordinary service on the ordinary resources configured by the network device.

[0179] In addition, in the present application, by limiting the data of the same service type to be grouped into the same transmission block, it is ensured that data of other service types will not be transmitted on the dedicated resources allocated by the network device to the terminal device, thereby avoiding the waste of dedicated resources.
